Fiber optics communications modules

摘要: A fiber optics coupler module has a portion defining spherical reflective surface characterized by self-conjugate plane having the property that point source of light in is imaged plane. The includes first and second optical transceiver terminals adapted to register source, detector, or end at each conjugate locations within passes fraction incident thereon, whereupon diverging from location through along path. Similarly further focusing means on side remote for imaging travelling path third location, also fourth location. In series embodiments, partially transmissive, wavelengths given range. dichroic surface. uses reflection grating collimated light.
